Fought just a month after the Battle of the Coral Sea, Midway was the first purely carrier battle. Skill, daring, and luck all played a part.
The attack on the island of Midway, which also included a feint to Alaska by a smaller fleet, was a ploy by the Japanese to draw the American carrier fleet into a trap. With the remaining American ships destroyed, the Japanese hoped to invade Hawaii.

At dawn on June 4, Japanese carrier aircraft bombed and heavily damaged the base on Midway. U.S. carrier forces, led by Rear AdmiralRaymond A. Spruance, had the advantage of knowing, through decryption of Japanese Navy communications, what the enemy was up to. When the Japanese aircraft returned to their carriers, Admiral Chuichi Nagumo decided to re-arm them with bombs for a second strike at Midway. While being serviced, the waiting American ships were detected. Nagumo eventually decided to change the arms load for an attack against the American ships. With torpedoes and bombs stacked, and fuel hoses snaking across their decks, the Japanese carriers made vulnerable and highly volatile targets.

Spruance launched an attack from the carriers USS Enterprise and USS Hornet against the Japanese carriers. Anti-aircraft fire and fighters shot down 35 of 41 torpedo bombers, but this action brought the Zeros down so low that the American dive-bombers could attack almost without opposition. Five minutes later, three Japanese carriers, the Akagi, Kaga and Soryu, were ablaze, abandoned, or crippled.

Aircraft launched from the remaining Japanese carrier Hiryu[?] struck the USS Yorktown, which was severely damaged, but survived this and a second attack, only to be sunk by a Japanese submarine on June 7. The same submarine sank the destroyer USS Hammann[?] which had been assigned to remain with the Yorktown. Aircraft from the Enterprise in turn attacked the Hiryu and set her ablaze, and damaged the destroyer Isokaze[?]. After this, Spruance, in concert with the forces on Midway, launched attacks that crippled and destroyed the Japanese cruisers Mogami[?] and Mikuma[?].

Having scored a decisive victory, American forces retired. The loss of four carriers stopped the expansion of the Japanese Empire in the Pacific, and put Japan on the defensive. It had been six months to the day since the attack on Pearl Harbor. Admiral Isoroku Yamamoto had predicted to his superiors that Japan would prevail for only six months to a year against the United States, after which American resources would begin to overwhelm the Japanese Navy.
